The curing or vnleenizing of the siirnee of rubber hose has hither'lo heen el'r'erleal oniy with comparatively Short lengwhs, (fifty or sixty feet), or where the erienxpt. has been mede to eine long lengths of horse, he curing hes been effected sectionally. with lhe result, fxu ihe whole length of hose ii.; not simulczineonelg. and similarly cured.

. The operation of my nieeliai'iisifi is as tol' lows:

The hose havingI been already manutantured, and coated with vuleanizalile material. is laid contiinuousl)Y within the spiral groove. rifhe upper plate is then lowered upon the other plate and one extremity of the hose. closed while 'to the other great pressure is applied extending' through the interior of the hose and. drivinnY its outer surfaces against the spiral grooves within which it lies. rlliis application ot' [luid presi sure to the .interior of the hoser` while it lies Vin'the grooves between the plates, is readily made, because the continuous spiral cylindrieal channel in which the hose lies, terminates at its end at the peripliei')Y ot the plates, so that the hose is accessible at this end for the application ol' internal pressure.

At the saine time the tenii'ierature of the plates is' raised by the proper application of steam or 'atei' to eli'ect the curing or vuleanizing o the material under the iiiessure to which the interior ot' the, hose is subjected, and by the combination o: pressure and teinpei-ature thus supplied, the material is cured. The curing thus performed at one operation.I is uniform throughout. and a veryinueh superior quality of loner length hose is thus produced than can lie turned out hy other machinesl or methods oi manufacture.

lla\'iiir thus described my invention, claim:

A, mechanism for @airingl long lengths of rubber hose, comprising in combination 0pposed horizontally disposed upper and lower plates, the opposed faces ol said plates being formed with complementary spiral grooves for receiving the hose, heating' means 'for each plate, means for introducing fluid pressure into said hose, and elevatingmeans for ythe upper plate to pei-init. the bodily placing or removal oi the hose in the groove of the lower plate, said n'ieans comprising a pluA rality of arms secured to and extending bevond the periphery oi the upper plate, and pressure actuated planners cooperating' with said outwardly extendingY ends of said arms.

In testimony whereof l have hereunto signed iny name at Philadelphia, Pennsyl# Vania, this second day et' August 1912.
